I missed this last week, and according to Google so did all the local media. Preservation magazine reports online that Sen. Robert Kennedy's murderer, Sirhan B. Sirhan, has sued the L.A. school board to stop demolition of the Ambassador Hotel. His contention is that the walls of the kitchen area where Kennedy was shot after an election victory celebration on June 5, 1968 contain evidence that more than one gun was fired. Sirhan's suit is separate from the one filed by the Los Angeles Conservancy and seven community groups trying to force the school board to save rather than raze some historic parts of the closed Wilshire Boulevard hotel. The artist's rendering of what a preserved lobby could look like comes from the Conservancy via Preservation Online, the website of the National Trust for Historic Preservation.
